<p>Welcome to Biogon PB. Before getting started, we need some information on the database. You will need to know the following items before proceeding.</p>
<ol>
	<li>Database name</li>
	<li>Database username</li>
	<li>Database password</li>
	<li>Database host</li>
	<li>Table prefix (if you want to run more than one Biogon Photoblog in a single database) </li>
</ol>
<p><strong>If for any reason this automatic file creation doesn't work, don't worry. All this does is fill in the database information to a configuration file. You may also simply open <code>gc-config-sample.php</code> in a text editor, fill in your information, and save it as <code>gc-config.php</code>. </strong></p>
<p>In all likelihood, these items were supplied to you by your ISP. If you do not have this information, then you will need to contact them before you can continue. If you&#8217;re all ready, <a href="setup-config.php?step=1">let&#8217;s go</a>! </p>
